Small 4mm × 7mm × 0.75mm QFN Package The LT®6604-15 consists of two matched, fully differential
amplifiers, each with a 4th order, 15MHz lowpass filter. The
fixed frequency lowpass filter approximates a Chebyshev
response. By integrating a filter and a differential amplifier, distortion and noise are made exceptionally low. At
unity gain, the measured in band signal-to-noise ratio is …
